ABOUT THE ROLE:
The Sandbox service team at SpaceXAI builds and maintains a secure, scalable system that gives our models safe, controlled access to computational environments. This infrastructure powers critical workloads across training and product, enabling models to run code, build software, interact with tools, and even control applications with user interfaces. We provision containers and virtual machines on large-scale clusters, granting models interactive control over these remote environments. Our work spans the full stack: from orchestrating massive jobs and resource scheduling at the cluster level, to fine-tuning filesystem performance on nodes. The Sandbox service enables Grok to safely run and test code in real-time for user queries, and supports reinforcement learning in training, where models interactively explore tools ranging from compilers to productivity apps.
BASIC QUALIFICATIONS:
- Expert knowledge of Rust, C++ or Go
- Familiarity with Python
- Deep experience with either Linux or Windows systems (familiarity with both is a strong plus)
- Experience with virtualisation and containerisation technologies (e.g., cgroups, KVM, gVisor, QEMU)
- Solid knowledge of the networking stack
COMPENSATION AND BENEFITS:
£107,000 - £262,000 GBP
Base salary is just one part of our total rewards package at SpaceXAI, which also includes equity, comprehensive healthcare and dental coverage, cash plan, income protection, life insurance, and various other discounts and perks.
